Vsock device related errors.

Variants

DescChainTooShortForPacket(u32, u32)

The total length of the descriptor chain ({0}) is too short to hold a packet of length {1} + header

EmptyQueue

Empty queue

EventFd(Error)

EventFd error: {0}

GuestMemoryMmap(GuestMemoryError)

Chained GuestMemoryMmap error: {0}

GuestMemoryBounds

Bounds check failed on guest memory pointer.

DescChainTooShortForHeader(usize)

The total length of the descriptor chain ({0}) is less than the number of bytes required
to hold a vsock packet header.

DescChainOverflow

The descriptor chain length was greater than the max (u32::MAX)

InvalidPktLen(u32)

The vsock header len field holds an invalid value: {0}

NoData

A data fetch was attempted when no data was available.

PktBufMissing

A data buffer was expected for the provided packet, but it is missing.

UnreadableDescriptor

Encountered an unexpected write-only virtio descriptor.

UnwritableDescriptor

Encountered an unexpected read-only virtio descriptor.

VirtioState(PersistError)

Invalid virtio configuration: {0}

VsockUdsBackend(VsockUnixBackendError)

Vsock uds backend error: {0}

IovDeque(IovDequeError)

Underlying IovDeque error: {0}

IovDequeOverflow

Tried to push to full IovDeque.

Trait Implementations

impl Debug for VsockError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for VsockError

fn fmt(&self, formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for VsockError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
